HENRI TRUXLER in PARIS. Innovations in combing machines.

Patented in the German Empire on February 25, 1879.

Fig. Ι of the accompanying drawing shows a longitudinal section of the machine.

Fig. 2 is a separate drawing of the supply for certain cases.

I. The feeding.

The rollers A with the pulp to be combed are unwound on the unwinding rollers BB and the same is guided by the rollers DD , which rest in bearings D ' which are attached to the arms G of the oscillating tongs G' GG ".

The sliver is advanced by 5, 6, 8 mm with each oscillation, depending on the nature of the material. The rollers DD, which are very close to the feed tongs, also form restraint tongs.

They get their movement through the locking cone F, which engages in the ratchet wheel E , which the latter is attached to the lower roller D.

The position of the two pivot points m and G ' to one another cause the locking cone and the roller D, which carries the ratchet wheel E , to each describe a special circle, so that when the apparatus has reached its lowest position in the companionway, the locking cone does so The ratchet wheel has pushed one tooth further, whereby, depending on the division of the ratchet wheel, the cylinders are unwound by 6.8 mm as desired.

The honeycombs D manage the feeding to the combers for cotton etc.

For fabrics from a longer pile, such as wool, etc., the inventor uses spiked rollers instead of cylinders hh'.h ", Fig. 2, between which the sliver continues. A locking cone similar to the one above moves these rollers.

In addition, a hacking stick d, which is located behind the forceps H " , penetrates the sliver at the appropriate moment, for which purpose it is connected to the comb / ', which is described below, or more correctly, to the arm /, who carries the comb / '.

It is consequently the Hechelstab d in the movements of the comb / 'take part.

II. The feeding and combing apparatus.

The upper gripper jaw H " and the lower gripper jaw G", which carry the feed rollers D , form the operative parts of the apparatus, which receives its movement from two thumbs L attached to the drive shaft K.

These thumbs L touch the rollers MM, which the latter are firmly on the tie rods J "which are connected at i to the arms H of the upper jaw H" .

The pivot point H 'of the upper jaw H " is further away from the jaws than the pivot point G of the lower jaw G".

But G ' is the fulcrum for the whole apparatus, whereas around H' only the jaw Ή '' rotates; H ¹ is further away than G ¹ in order to obtain a greater lever length for better pressure.

The lower jaw G ″ is attached to the arms G and thus swings around the pivot point G '.

On the tie rods J are fixed two rollers P ' which come into contact with a protrusion on the lower side of the arms G; these rollers P carry the arms G and the lower jaw. The other cheek H " attached to the arms H is the main part of the whole apparatus.

When the tie rods J go up and down, the lower jaw PGG follows "only the upper HH".

In addition, the projection P with which the lower jaw rests on the rollers P ' is shaped in such a way that the pliers are only slightly opened in the position indicated. On the other hand, when the rods go down, it allows the lower jaw, which always rests on the rollers P , to move away from the upper jaw and in this way to bring about the complete opening of the tongs at the moment when the locking cone F moves the feed device . In the last part of the descending movement the lower jaw meets two projections O before the thumbs L attached to the shaft K have completed their course; when at last the lower jaw is held up in this way, the upper one lies down

Continuing its descending motion, cheek on the lower cheek.

The upper rollers M of the rods J contacting the thumbs L have fixed pins. The pins of the lower rollers M are supported in coulisses of the rods J, these rollers M are held in contact with the thumbs by the pressure of the springs N and thereby impart a pressure against the upper rollers, whereby the larger coulisses control the movements in the rods J, through which the wave K passes. So when the lower jaw rests on the projections, the upper jaw presses on it, while the thumbs L press strongly against the lower rollers M at this moment, and then the thumbs move a few millimeters, depending on the regulation, from the fixed rollers Remove M , the springs N give just as much and transfer their strong and elastic pressure to the pliers.

Arriving in the lower position, the jaw G "has come into contact with the trough Q" and the tuft, held by the pliers, lies on this; the captured material is now combed.

The trough Q " is placed concentrically to the combing drum Q ' , and holds the tuft in the needles which sit in the combing drum Q' , as the drawing shows.

The movement of the needles thus takes place while the thumbs L do not act on the feeding device.

The trough Q ″ sits on the two lever arms g which are attached to the shaft Q of the combing drum Q ′ and each of which carries a roller η which is moved by a thumb Z ′ fixed on the shaft K.

At the moment when the levers G and the hollow Q " stand still, the comb segment of the combing drum with its needles, the tips of which pass very close to the concave part of the hollow, brushes through the tuft and combs it out. As soon as the last row Needles at the trough Q ″ is over, it suddenly rises by 2 to 3 mm and thereby erects the tuft again, which had bent downwards during the combing. This movement must be completed before the thumbs L move the feeding apparatus again.

III. The tapping machine.

The combed and straightened tuft can now be inserted into the first stripping tongs SS ' , and this opens at this moment in order to receive it.

The shaft R, which carries the two tongs, makes half the number of revolutions of the shaft K.

The jaws S are attached to the parts ί located on the disks T " , which slide in cast-iron coulisses on the disks.

The disks wedged onto the shaft R move the entire apparatus as they rotate. The parts s which carry the jaws S are also moved by the latter, since their rollers T ' touch the thumb T attached to the frame.

The movement of this apparatus is done by a gear train and is consequently continuous. .

The change in the position of the parts described is therefore quite definite Relation to the action of the feeding, combing, and feeding apparatus.

The pliers consist of the jaws, S ¹ S ¹ . These collectively make the same eccentric rotation.

The arms s' which support the jaw S ' are mounted on the same pegs which are attached to the parts s and on which rollers T' turn. The springs S ″ are attached to the same peg, while the other end of the latter is attached to the arms s' .

These springs S " therefore go from the pin T ' of one pair of pliers to the pin s" of the arm s ^{1 of} the other pair of pliers.

In this way, the springs S ″ simultaneously cause the one pair of pliers to be pressed against the eccentric curves of the fixed thumb T and to close the other pair of pliers.

If, therefore, a pair of rollers T ', which is lifted by the thumbs T and takes the parts s with it, pushes the corresponding pliers SS' outwards, these pliers open, because the arms s' by being against the button cTan, which is fixed on the disk, must be forced to swing around the point of rotation T ' , while at the same time the roller T · ■ approaches the center point R.

So the springs are tense when the Pressure is necessary, and go back when the pressure is to cease.

The wiper rotates in the direction of the arrow and measures the gap between it and the feeding device about 5 mm.

At the moment when the feeding device rises shortly before it comes to a standstill, the first jaw of the stripping device begins under the action of the fixed eccentric thumb Txma of one pin U, against which the corresponding opening and closing arm s' abuts, the corresponding forceps open to allow the beard to enter.

Although the two apparatuses do not have the same speed, they agree in so far as they increase together as the speed of the feeding apparatus is decreased. This reduction in speed is achieved by a corresponding construction of the thumb L.

It rises the combed and straightened fiber beard now, while opposite the first open pliers complete their upward movement.

pulls. The tip of the whiskers comes into the open forceps while the organs approach one another; as soon as the feeding and the stripping apparatus are exactly opposite one another, the tuft is grasped by closing the jaws .S S ' . At this moment the tuft also gets into the cutting comb /, which also rotates around G ' like the feeding device and which has stood still until then.

The thumbs L, which have not yet completed their 'run, continue to lift the feeder and to pull the pre-cutting comb /' through the lever arms / beyond the drawn rest position until the adjusting screw of the latter hits the frame.

In this way, the fiber material remains in the cutting comb and the latter retains its position to the feeding apparatus, which then stands still while the Abreifsapparat its rotation continues, pulling the fibers through the cutting comb.

The pliers SS ' moving away from the feeding device simultaneously moves towards the stripping device by means of the firm thumb T.

This movement increases the distance between the two apparatuses described from each other and through this return movement both the short and the long become Fibers drawn through the cutting comb without changing the speed of any part.

For this reason, the gait is extraordinarily smooth and gentle for both short and long fibers this machine can therefore be given a greater speed than similar ones.

The pricking comb is usually very fine to comb the end of the fibers; the The device described here allows it to be adjusted according to the material and the distance the feeding and stripping devices from each other as desired, single, double or triple close. ,

When the feeding device goes down again, the tuft remains in the pre-cutting comb, until it lays down on the frame with its adjusting screw and stops moving. Through the Downward movement of the feeding device, the tuft emerges from the. Comb out. This movement takes place imperceptibly, as if the cutting comb were an independent one Subject to movement.

The position of the pricking comb has the consequence that no exit remains because the whiskers take everything away.

IV. Doffer roller and brush. The doffer roll X is provided with a card lining; she picks up the combed beards pulled from the cheeks. After the jaws have pulled the tuft through the pricking comb, they pass in front of the doffer X and move outwards under the action of the eccentric thumbs T and at the same time the button U causes the jaws to open, which only hold the combed tuft on the head . The entire end of the fibers protruding beyond SS ' lies with its outermost end in the roller and is pressed in by the rotating movement of the opening forceps. The latter, by opening, releases the tuft, which is immediately pressed S to 6 mm deep by the coating brush V into the doffer roller. The following brush only rotates when it comes into contact with the doffer. One of these brush rollers V is attached behind each tong SS ' between the journals s ″ from which the springs S ″ are suspended.

The brush is held between these pins.

The action of the second pair of jaws is similar to that of the first. It sets the following Tuft on the doffer roll approximately in the middle of the length of the previous tuft so that the end coming from the first pair of jaws is from the head the second is covered by moving the stripper roller slowly in the direction of the arrow rotates.

The brushes V reinforce, connect and lay the fibers on top of one another and in one another to finally form a coherent fiber ribbon.

The fleece, detached from the roller by a hook X ' , then goes combined into a guide funnel, then between two pulling rollers YY, which compress the tuft strongly, transforming it into a band, which gets into a rotating sheet-metal cylinder.
